BT30 is a standard tool holder taper used in CNC machines, especially medium-sized machining centers and lathes.
- A reducing arbor (spindle adapter) allows smaller or different-type tool holders to fit onto a BT30 spindle.
- Common uses include:
- Adapting different taper types to a BT30 spindle
- Using smaller diameter milling, drilling, or turning tools
- Increasing machining flexibility and reducing tool costs
Advantages: - Enables a wider range of tools on an existing BT30 spindle
- Easy mounting and removal
- High precision and secure clamping
